UX-08 phase 2b: short, plain status rows and page banners

Every Commissioning row and every page banner is now worded in
app/messages.py (row_*, banner_*): one sentence of at most 15 words, a red
row up to three sentences so a latch still says how it clears, banners at
most 12 words. No row names a Home Assistant entity: sensors by their
setting, solar sources by their place in the list. Reason codes and limits
stay on the log line and event list; rows keep the numbers a reader acts on.

UX-07 item 1: ClampWatchdog counts over-rating and integrator-bound
engagements separately, and after an episode each count shows under its own
alarm's title instead of both under "output clamp".

No row colour, visibility or banner order changed. Rows carry an "id" so the
tests pin meaning rather than wording. The row and banner kinds leave the
allowlist (200 -> 168, cap equal). DOCS.md gains "Status page"; choices are in
DECISIONS/UX-08-short-notifications.md.
